Albertosaurus was a giant carnivorous dinosaur that lived a few million years before T-rex appeared. Albertosaurus means "Alberta lizard" in Greek, where many of its fossils have been discovered, and sarcophagus is the Greek word for "carnivore."

During its time, Albertosaurus sarcophagus was the top predator in Upper Cretaceous Canada. This ferocious carnivorous dinosaur was similar to Tyrannosaurus; both had reduced forelimbs and a large skull and jaws, although Albertosaurus was somewhat smaller. 

Albertosaurus had predatory behavior such as bipedal movement, bird-like hollow bones, tiny forearms, and moved quickly. Albertosaurus also had some key differences with Tyrannosaurus such as its skull was quite a bit thinner, and its teeth were not well adapted for bone crushing.

The Albertosaurus was somewhat smaller. Albertosaurus was about 9 meters long and a foot high at the hips and weighed up to 3 tons. The jaws of Albertosaurus possessed numerous large, sharp teeth; the lower jaw had 14 to 16 teeth; the upper jaw had 17 to 19 teeth, which were cropped and serrated. 

Albertosaurus lived in a semi-tropical environment with lots of vegetation. Albertosaurus would be hunted by prey much larger or equal to its size. 

Is an Albertosaurus a carnivore?

Definitely! Albertosaurus was the top predator during its time, either hunting prey larger than or equal to its size.

What was the Albertosaurus like?

Albertosaurus was a large dinosaur that lived a few million years before T-rex appeared. It walked on two legs, hollow bones like a bird, small front arms and the ability to move quickly. It was about 9 meters long and a foot high at the hips and weighed up to 3 tons. The jaws of Albertosaurus possessed numerous large, sharp teeth; the lower jaw had 14-16 teeth; the upper jaw 17-19 teeth, which were trimmed and serrated. They had three functional toes that gave this dinosaur a bird-like footprint.

How fast can Albertosaurus run?

The speed of Albertosaurus was approximately 14 to 21 km/h.

What are the features that can be found in Albertosaurus?

Albertosaurus belonged to a group of theropods of the Late Cretaceous period. 
The following are the features that can be found for theropod dinosaurs:

  1. Speed and agility.
  2. Carnivorous diet.
  3. Sharp, sliced teeth and well-developed jaw muscles.
  4. Biped walking.
  5. Strong legs with bird-like feet, with three toes and claws.
  6. Hollow bones (like those of birds).

Which dinosaurs lived with Albertosaurus?

Albertosaurus lived among the hadrosaurs, including Edmontosaurus, eratopsians, ornithohominids and several species of carnivorous theropods.

How much did Albertosaurus weigh?

Albertosaurus could grow up to 1,300 - 2,500 kg.

What does an Albertosaurus eat?

Albertosaurus was a large predator that preyed on other dinosaurs, such as the duck-billed dinosaur.

How big is an Albertosaurus?

Albertosaurus was about 9 meters long and 1 foot high at the hips and weighed up to 3 tons.

In what time period did Albertosaurus live?

Albertosaurus was a giant carnivorous dinosaur that lived a few million years before T-rex appeared. It lived during the Late Cretaceous period, about 70 million years ago.
